This is the record for what went well and what didn’t go well in the process of migrating the *.consumium.org sites (except https://c.consumium.org, that’s in Espoo)

This migration was completed on 2016-06-09. I would like to extend a warm you to https://TransIP.eu for showing compassion in my predicament and offering to credit me some of the costs incurred by requiring 2 servers for a period of a time.

<spam>Their operation is really top-notch and I have never had outages with them that I would not have been responsible. Ever since I started hosting free social media with them in July 2013 the service has been outstanding and their control panel does include ability to take snapshots of system disks and a VNC just in case someone is not comfortable working with cli. The first time I saw the VNC in the control panel and it started to show the Debian GNU/Linux white-on-black bootup in my browser I was impressed.. Then it moved to run level 6 and I was naturally like “Whoa! It can do that!”. TransIP.eu is maybe not the most inexpensive hosting guys out there at the moment but I tell you their service level and its consistency are worth all the extra money. SSD system disks are spaceous and very fast and just as soon as http://maidsafe.net/ starts I’ll be purchasing at least one 10€ unit of 2,000GB big storage (which can be grown to 400,000GB, slightly under 400TB). Scp’ing between 2 servers in the same data center in Netherlands I was able to clock 101 Mbit/s speed. That is almost a gigabit / second, normal HDD couldn’t handle that.</spam>

Debian8 -> Debian8 migration of 4 free social media instances. Debian GNU/Linux, Nginx for web server, MariaDB for RMDBS and ruby, PHP and python as langauges the services run on

Migration of diaspora* to a new server

https://d.consumium.org (how to install diaspora* freesome on Debian GNU/Linux)
diaspora* is the biggest and best known of the free social media. It has innovative features though is somewhat limited due to the creators thinking really hard about protecting the consumer from possible privacy related threats. The software is high quality and reliable. It uses a asymmetric sharing arrangement that is diametrical to twitter’s

The original raison d’être for the old server called Debian7. The name is not very well chosen and misleading since the machine was dist-upgraded to Debian8 stable without hick-ups. Diaspora* was originally installed in July 2013 which at the time took couple of days

Grabbed the database, app/views/home and public/uploads and inserted those into place and the pod looks fine now after the migration.

Email was more of an hassle and is covered in a separate paragraph you’ll find down this page.

– GNU social is a handy microblogging service.This instance was installed in 2016. Should pose no problems. MySQL was replaced with MariaDB during installation of this with no problems. Update: GNU social migration was the first one to be done. Grabbed the database (which contains the confs) and the ‘avatar’ and ‘files’ directories. Shut down. Put those in place and restart web server and GNU social was up with apparently all the old information from the previous box.

If you are getting an Error 400: After the migration the GNU social has been doing the same thing as before.. It often when trying to microblog gives an error “400”. Here one just needs to know to hit ctrl-r, no need to even hit ctrl-a ctrl-c, ctrl-r, ctrl-v as the software preserves what was written into the textbox.

Interesting point about Hubzilla and Friendica

Friendica and Hubzilla leverage the same instructional capital and best-practice which leads to that their installation instructions have many portions in common.

Migration of Hubzilla to a new server

https://hub.consumium.org – (how to install Hubzilla freesome)
Hubzilla is a very high quality software and it has always worked just like the label said. It’s use of channels is intuitive as a way of interacting with other people.

This will probably not have the old database restored because when I originally installed this I didn’t realize the point is to have many many channels but just one login. Of course it might be possible to restore the database but manipulate it so that the Consum(er)ium relevant channels would be under the same user

Well I did restore the old database.

Pretty much everything that was needed for installation of Hubzilla was already there. Just needed to run ‘sudo aptitude install mcrypt php5-mcrypt’ and installed the Hubzilla, Stopped Nginx and dropped in the database and the user uploads located in /var/www/hubzilla/store and it seems to work fine.

Friendica is the least learning curve free social media solution for the people escaping Facebook more and more often.

the freesome of least steep learning curve for the people who want to free themselves of Facebook every now and then.

Friendica migration did not require copying over more than just the database as Friendica saves the uploaded files in the database and not flat file system.

Dealing with outgoing and incoming email

Getting email arrangements to work in a safe and reasonable way is by no means as easy as one may think at start. diaspora* email was configured to use SMTP over a TLS encrypted hop over to https://gandi.net‘s SMTP server. Took a while to figure out but I am guessing this will make the email look better to spam filters as the “origin” is under the same domain as the machines given in the MX records in DNS to be the Mail eXchange servers for consumium.org

‘sudo aptitude install sendmail’ installs sendmail, an MTA this is apparently all that is needed for PHP’s mail()-function to work.

The migration plan (and how it went)

(Note: to lazily get all the dependencies and hope there wasn’t old junk you could follow this post http://juboblo.gr/index.php/2015/12/02/original-howto-migrate-gnulinux-to-bigger-disk-with-clean-install-and-grab-all-apt-gettable-software-settings-and-files/)

Migration of system settings

Update services to latest version so you get the same exact version when you reinstall each service from latest release [✔]

Grab TLS key and cert – Remember to keep the key safe [✔] (note: exposing the server.key usually kept in /etc/ssl/private is very dangerous as it will expose all communications encrypted with that key)

Grab firewall settings allowing traffic to 22, 80 and 443 [✔] NMAP security scanner is great copyleft free tool for looking at this. tip: ‘nmap localhost’ inside the firewall and ‘nmap the IP address” from outside the firewall will be very useful scans for verifying firewall settings.

Grab confs:

/etc/nginx/nginx.conf [✔]

/etc/nginx/sites-enabled/nginx.conf [✔]

Grab home dir [✔]

Grab logs [✔]

/var/log/nginx/access.log [✔]

/var/log/nginx/error.log [✔]

Then decided to grab all of /var/log into a .tar.gz, Is only logs, cannot hurt and [✔]

Mass grab /etc and /var/www for later reference when the old server is recycled and resources returned to cloud.

Get new server. [✔] Remember to install an ssh server when installing the software or you’ll be unable to access via ssh. Only if hosting guys provide a Virtual Network Console you can fix this problem there

Add self to sudoers [✔]

Restore home dir contents [✔]

Install Nginx [✔]

Put logs, key, cert and nginx.conf in place [✔]

Repeat following steps for each service

Install dependencies [✔]

Install new service clean [✔]

NOTIFY USERS THAT NOW IS FEW HOURS OF DATA LOSS IF YOU POST Better idea: When all is ready with the new installation in place and you are thus ready to start the DNS change propagation tell people that the database will be frozen when the old machine is “unreachable” due to the DNS already pointing to the next machine.

@SenSanders

Capitalism is going deeper into crisis and the current status quo (which Clinton seems to want to hold intact) that no replacing jobs are created and there seem to be no politicians pushing for planetary basic income funded from sharing the revenue streams generated by invested capital.

Due to human productivity the feasibly employable capital is growing constantly (unless we already dunn wreck the weather and will suffer from it) and this in conjunction by the scientific-technical advances, new service innovation and vast efficiency gains from self-service automation and full automation in ICT drives growth of service productivity. These should enable to pay planetary basic income.

Take away cab driver, bus driver, delivery truck driver, trucker and farm equipment operators’ jobs is what the automators are now proposing so you see that this decline of capitalism ain’t gonna be happy time for the middle-class and proles either.

I know the people who publicly advocate total despotic enforcement of maximal greed everywhere all the time by the invisible green hand (read: mostly republicans) fathomed by Adam Smith don’t want it totalitarian for those they consider their kin. Maybe peoples of the Earth need to rethink how they divide to kin/non-kin.

Call me commiemist, I’ll slice, dice and red red hot hot salsa salsa till everyone’s gotten something to eat and if there is more resources then I’ll crêpes with jam and whipped cream for dessert.

Here is an infographic:

“When you increase the buying power of the not-so-well off ones it all goes to their consumption which drives the economy forward. When you tax the rich it doesn’t come out of their spending but their (highly speculative and debt levered) investments (which are often not connected to the development of the real economy at all).”

Resource Monitor is a KDE5 Plasma Plasmoid Widget companion to the System Monitor. Install instructions in Muon Discoverer. One dependancy must be installed. It sits in your panel and reports CPU load and frequency, RAM and swap usage with tiny letters and numbers and graphics. Here seen in 2x high panel height

Thinkpad Fan Control is a fan RPM control software written in C for the Thinkpad series of laptops. Apparently the normal controller has a ceiling at 4,500RPM but according to the internets the fan can be instructed to go 5,500RPM raising the noise pitch and volume slightly.

System monitoring software for Windows

Core Temp is a freeware Windows program and reports real time temp sensor data ( prlly algorithmically smoothed but much more stable ) and real time CPU frequency multiplier and frequency reading.

CPU-Z by CPUID is another good free-of-charge Windows program that will give you lot of information about your system also including the frequency multiplier used at each time

Synopsis of the original problem

Not like this. Psensor showing temperatures where the user is susceptible to system shutting down because of a trigger temperature has been reached or exceeded

Had a machine with a weird temperature problem here… It’s a 2011 Lenovo ThinkPad X201 with a 1st generation i5 known as Arrandale. CPU temperature control, maybe voltage control, maybe amp control is not working correctly in #Kubuntu. (UPDATE: Sandy Bridge, Ivy Bridge and newer intel systems should use the Intel P-State governor. Installation instructions for [K]ubunu here)

Temperature seems to be mostly dependent on the frequency of the CPU with some correation to load. Reported CPU fan rotation speed is 4,000-4,500 RPM and does not adequately respond to the heat situation.

(UPDATE: Directing high pressure pressurised air into the cooling elements while machine unpowered seems to have remedied the problem.)

#GNU/#Linukka heat shutdowns causing system being unusable. Before anyone starts about the GNU/Linukka treating the system and therefore the user more badly then a Microsoft Windows I must say that air conducts have not been cleaned and silicon heat paste has not been changed to fresh, new. I gonna get supplies to do that when I run into shop.

In Kubuntu15.10 GNU/Linukka burns the chip at ~ 90C ~ 2.0-2.5Ghz operating speed causing emergency shutdown because of temperature because the readings viewed in Psensor may flux 15-20C somewhat interdependent of CPU load. Windows 7 keeps the CPU ~ 1.5-2.0GHz quite independent from the load and the temps are in the acceptable ~ 70C zone with only 2-4C variance in the readings reported by CoreTemp.

#Solution:

* Bought a pressure air can and blasted the visible from exterior heat sink
